GeForce GTS 150 vs GeForce GTX 460 SE

Intro

Compare all of that to the GeForce GTX 460 SE, which has GPU clock speed of 650 MHz, and 1024 MB of GDDR5 memory set to run at 850 MHz through a 256-bit bus. It also features 288 SPUs, 48 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTS 150		141 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 9 Watts (6%)

Memory Bandwidth

The GeForce GTX 460 SE, in theory, should be a lot faster than the GeForce GTS 150 in general. (explain)

GeForce GTX 460 SE		108800 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 76800 (240%)

Texel Rate

The GeForce GTS 150 will be much (more or less 52%) better at AF than the GeForce GTX 460 SE. (explain)

GeForce GTS 150		47360 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 16160 (52%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 SE is a better choice, and very much so. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 8960 (76%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
